SECTION I - CLASS DEFINITION

This Class provides for apparatus and corresponding methods for processing an electrical signal, representative of a sequence of images, in which the light variation composing the images may change with time (e.g., natural or " live" scenes, etc.) for recording or reproducing.

The processing involves the following steps: (a) receiving an electrical signal representative of a sequence of images from a local (e.g., camera, etc.) or remote source (e.g., broadcasting station, satellite, cable, etc.) and converting the received sequence of images into a form suitable for storage, which form may or may not be reproduced later, or (b) converting retrieved information from a storage medium into a sequence of images.

This Class also provides for apparatus or processes for recording a single image of a sequence of images (i.e., a still or frame) using a dynamic recording device having relative movement between a transducer and a medium.
